Westinghouse 621830 Air Handler Motor 1/3 Hp 3 Speed

Product Description

The WESTINGHOUSE 621830 is a replacement blower motor designed for indoor air handler units. Rated at 1/3 horsepower and operating on 230 VAC at 60 Hz, this motor delivers three-speed operation to support variable airflow demands within the air handling system. It is a direct replacement component installed by licensed HVAC technicians during routine motor failure diagnosis or scheduled equipment maintenance. The three-speed configuration allows the system to stage airflow across heating, cooling, and fan-only modes without additional control hardware.

This motor is intended for residential indoor air handler applications. It is specifically listed for use on WESTINGHOUSE GB3BM-030K-AB and GB3BV-030K-AB air handler units. These units are typically installed in split-system configurations where the air handler is located indoors and paired with an outdoor condensing unit. The motor drives the blower assembly responsible for circulating conditioned air through the duct system.
